This overview gives a short introduction to the Waved Hub, and covers its purpose, its physical connections and some details about the hardware.
In-depth explanations, about the Hub's network interfaces are covered under the Network Configuration section.
Waved Hub is the heart and brain of our system, it's responsibilities includes:
Gathering and analysing data from the sensors.
Making decisions regarding volume automation.
Communicating with end-users.
and logging data.
The Hub is based on a Raspberry Pi and uses an SD-card as storage. There is a Zigbee module attached to the Raspberry Pi, which serves as the coordinator for the Zigbee mesh network of the Waved sensors. All communication between the sensors and the Hub goes over the Zigbee network.
In the unlikely case of a hardware failure on the Raspberry Pi, the Zigbee module and SD-card can be moved to another Raspberry Pi, and the Waved Hub will work as before.
Raspberry Pi provides many possible connections, however Waved Hub only uses a few of them. The ethernet port is used for connecting to the internet, and in many cases to connect to digital sound systems. The USB-C port is used for power supply.
In installations where using a cabled connection to the internet is either impossible, or highly impractical, the Waved hub can also connect to the internet via Wi-Fi.
